Efforts have been made to ensure that the information on this site is accessible to as many visitors as possible.
If you find that the text is not a comfortable size for reading, you can adjust it's size. There are several ways to achieve this:
Most browsers allow you to change the text size. Generally, the text size option is an option in the 'View' menu and there are often keyboard shortcuts (e.g. 'CTRL' & 'plus' to increase the size). The exact controls vary according to the browser and operating system, so please see your browser help pages for details.
If you find that most of the sites you visit display text at an uncomfortable size, many browsers allow you to set the default text size for all web sites that you visit. Again, please see your browser help pages for instructions on setting this in your particular browser.
You can also use the '—' and '+' controls at the top right near to this help page to change the text size. Click the 'R' symbol to reset the text to it's default size.
In addition, you can also choose the theme (colour scheme) that you are most comfortable with.
